2. 1. Chlorine Induced Corrosion in Biomass and Waste Fired Boilers: Laboratory and Field Investigations

   Author : Nicklas Folkeson; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; austenitic; chloride; biomass; high temperature corrosion; ferritic; waste; steel;

   Abstract : The fireside corrosion in biomass and waste fired boilers is widely believed to arise from the presence of chlorine-containing compounds in the fuels. Although many researchers have studied the influence of such compounds on the high temperature corrosion of various steels, the mechanisms underlying chlorine-induced corrosion are still poorly understood.

4. 2. Superheater corrosion in biomass and waste fired boilers : Characterisation, causes and prevention of chlorine-induced corrosion

   Author : Peter Viklund; Christofer Leygraf; John Nicholls; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; high temperature corrosion; waste; biomass; superheater tubes; steel; alkali; chlorine; sulphur;

   Abstract : Biomass and waste fired boilers suffer severely from corrosion of critical components such as superheater tubes. In this work high temperature corrosion of superheater alloys, and methods to mitigate the problem, have been investigated by laboratory studies and controlled field exposures in commercial boilers.

5. 3. Catalytic combustion of gasified waste

   Author : Henrik Kusar; KTH; []
   Keywords : Catalytic combustion; Gasified waste; LHV-fuel; RDF; Biomass; Selective catalytic oxidation; NH3; NOX; Palladium; Platinum; Hexaaluminate; Garnet; Spinel; Deactivation; Sulphur; Poisoning;

   Abstract : This thesis concerns catalytic combustion for gas turbineapplication using a low heating-value (LHV) gas, derived fromgasified waste. The main research in catalytic combustionfocuses on methane as fuel, but an increasing interest isdirected towards catalytic combustion of LHV fuels. READ MORE

   Abstract : This thesis is a contribution to feminist laboratory studies and a critical engagement with the natural sciences, or more precisely research on the biochemical workings and deadly relations of Alzheimer’s disease emanating from a year of field work in a Drosophila fly lab. The natural sciences have been a point of fascination within the field of gender studies for decades. READ MORE

7. 5. Alkali Induced High Temperature Corrosion of Stainless Steel - Experiences from Laboratory and Field

   Author : Jesper Pettersson; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; KCl; 304L; Biomass; Corrosion; Chlorine; Chromate; Waste; Deposit;

   Abstract : The high temperature corrosion of steam superheaters is a major obstacle that has to be overcome in order to increase the electricity generating efficiency of power boilers burning biomass or waste. This thesis addresses this issue by a combination of well-controlled model experiments in the laboratory and short and long term field exposures using cooled probes in full-scale biomass and waste fired boilers.
